How to vent a shed roof

Updated February 21, 2017

Venting a shed is a good way to get proper air circulation and help the air flow in general. There are a few ways to vent a shed, but the most common is to vent it from the roof. Venting a shed is similar to venting a house's roof. It will follow the same general principles and the same type of roof vents can be used. When venting a shed it is always important to seal it up properly so the outside elements can not get in. With the proper instructions any shed can be vented in almost no time.

Climb a ladder up to the roof of the shed and pick a spot for the vent to be placed. Measure the size of the vent that will be installed and mark it on the roof by driving a nail into each corner where the vent will go. Make sure to drive the nails through so they are visible from the inside of the shed.

Remove the shingles from the area inside the nails with a shingle stripper, being careful not to damage them so they can be reused if necessary. Drill a hole in each of the four corners of the plywood where the nails were located.

Cut out the rest of the area with a circular saw. Install 2-inch by 4 -inch blocking along the inside of the hole around the edges. Cut the lumber to size with a circular saw and screw the pieces into the rafter along the inside edges of the hole.

Run a bead of caulk along the bottom of the roof vent and lay it on the hole at the desired location. Push down firmly to adhere it to the blocking along the inside of the hole. Insert roofing nails into the flashing along the edge of the roof vent and through the blocking. Continue all the way around the vent.

Install the shingles back over the base of the roof vent. Nail the shingles back in place and inspect the area to make sure everything is sealed properly. Climb down the ladder carefully and make sure all nails and materials are removed from the roof of the shed.


Always wear safety goggles when working with a circular saw to avoid injury to your eyes. Take precautions when working with a ladder. Make sure it is always on steady and stable ground when in use and be careful when climbing back down.
